Make SCEVCallbackVH::allUsesReplacedWith update the old SCEVUnknown object, as it may still be referenced by SCEVs not cleaned up by the use list traversal. Also, in ScalarEvolution::forgetValue, only check for a SCEVUnknown object for the original value, not for any value in the use list, because other SCEVUnknown values aren't necessary obsolete at that point. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109570 91177308-0d34-0410-b5e6-96231b3b80d8
